87124651 divided by 718 
We want to figure out the number of times 87124651 can be divided by 718.

Step 1:
When dividing 8 by 718, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Grab the next digit (7) from the dividend, add it to 8, then carry on: 87 / 718

Going ahead to step 2:
The number 718 fits into 87 0 times, leaving a remainder of 87.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 87 after subtracting 0 from 87.
Include the next digit (1) from the dividend after 87, then repeat: 871 / 718

Going ahead to step 3:
When dividing 871 by 718, we get 1 with a remainder of 153.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 718 from 871, we get 153.
Bring next digit (2) of the dividend behind the 153 and repeat the process: 1532 / 718

Going ahead to step 4:
718 can be fit into 1532 2 times, resulting in a remainder of 96.
Use 2 as the next digit of our solution. 
Result so far: 12.0
If we take 1436 away from 1532, we end up with 96.
Append the next digit (4) from the dividend to 96 and continue with: 964 / 718

Step 5:
964 divided by 718 is 1 with a remainder of 246.
Record the quotient 1 as the next digit in the result. 
Result so far: 121.0
The remainder is 246 after subtracting 718 from 964.
Fetch the next digit (6) from the dividend, attach it to 246 and continue: 2466 / 718

Step 6:
2466 divided by 718 is 3 with a remainder of 312.
The next digit of our result is 3. 
Result so far: 1213.0
Subtracting 2154 from 2466 leaves us with 312.
Append the next digit (5) from the dividend to 312 and continue with: 3125 / 718

Going ahead to step 7:
If we divide 3125 by 718, we get 4 and a remainder of 253.
The number 4 becomes the next digit in our result. 
Result so far: 12134.0
If we subtract 2872 from 3125, we get 253.
Include the next digit (1) from the dividend after 253, then repeat: 2531 / 718

Step 8:
When dividing 2531 by 718, we get 3 with a remainder of 377.
The next digit of our result is 3. 
Result so far: 121343.0
Subtract 2154 from 2531 to get 377.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3770, and continue the process.

Advancing to step 9:
718 goes into 3770 5 times with a remainder of 180.
Record the quotient 5 as the next digit in the result. 
Result so far: 121343.5
Deduct 3590 from 3770 and we're left with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Step 10:
When dividing 1800 by 718, we get 2 with a remainder of 364.
The next digit of our result is 2. 
Result so far: 121343.52
Subtract 1436 from 1800 to get 364.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

Going ahead to step 11:
3640 divided by 718 is 5 with a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 121343.525
The remainder is 50 after subtracting 3590 from 3640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 12:
When dividing 500 by 718, we get 0 with a remainder of 500.
The next digit of our result is 0. 
Result so far: 121343.525
Subtract 0 from 500 to get 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Moving on to step 13:
When dividing 5000 by 718, we get 6 with a remainder of 692.
Record the quotient 6 as the next digit in the result. 
Result so far: 121343.52506
Subtract 4308 from 5000 to get 692.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6920, and continue the process.

On to step 14:
The number 718 fits into 6920 9 times, leaving a remainder of 458.
The next digit of our result is 9. 
Result so far: 121343.525069
Subtracting 6462 from 6920 leaves us with 458.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4580, and continue the process.

Moving on to step 15:
If we divide 4580 by 718, we get 6 and a remainder of 272.
Put 6 as the next digit of the answer. 
Result so far: 121343.5250696
If we subtract 4308 from 4580, we get 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

Going ahead to step 16:
718 goes into 2720 3 times with a remainder of 566.
Record the quotient 3 as the next digit in the result. 
Result so far: 121343.52506963
If we take 2154 away from 2720, we end up with 566.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5660, and continue the process.

After the division, we end up with 121343.52506963 and a remainder of 5.66e-07.
